CONSTITUTION: A polyurethane apex composition for a polyurethane tire is composed of mixing prepolymer with chain extension material in the ratio of 1:0.6¯1. The prepolymer is manufactured by reacting polypropylene glycol being 650¯2000 molecular weight or polytetramethyelene glycol ether with diisocyanate in the ratio of 1 to 2. The chain extension material comprises methylene-ortho chloroaniline or methylenediamine.

Description

에이펙스(APEX)가 보강된 폴리우레탄 타이어Polyurethane tires with APEX reinforcement

본 발명은 폴리우레탄 타이어용 에이펙스(APEX) 조성물 및 이를 이용하여 제조된 에이펙스가 보강된 폴리우레탄 타이어에 관한 것이다.The present invention relates to an APEX composition for polyurethane tires and an apex-reinforced polyurethane tire manufactured using the same.

종래의 폴리우레탄 타이어의 경우, 일반 고무타이어에 존재하는 에이펙스가 없으며, 전체구조가 인너(Inner)부, 사이드(Side)부, 트레드(Tread)부, 비드(Bead)부, 벨트(Belt)부, 카커스(Carcass)부로 구성되어 있어 성형방법이 비교적 단순하여 제조가 간편하다는 장점은 있었으나, 에이펙스부가 없는 관계로 타이어의 성능 중 특히 조종성과 주행안정성이 취약한 결점이 있었다.In the case of conventional polyurethane tires, there is no apex present in general rubber tires, and the overall structure is an inner part, a side part, a tread part, a bead part, and a belt part. It is composed of a carcass, and the molding method is relatively simple, so it is easy to manufacture. However, since there is no apex, there is a drawback in that the tire performance is particularly poor in maneuverability and driving stability.

이에 본 발명에서는 종래의 폴리우레탄 타이어의 결점을 개선하기 위하여, 폴리우레탄 타이어에 적합한 폴리우레탄 에이펙스 조성물을 제조하고, 이를 이용하여 폴리우레탄 타이어에 에이펙스부를 보강함으로써 기존의 폴리우레탄 타이어보다 주행시 사이드윌의 굴신폭을 줄여 우수한 조종성능과 주행안정성을 갖는 폴리우레탄 타이어를 얻을 수 있었다.Therefore, in the present invention, in order to improve the defects of the conventional polyurethane tire, by manufacturing a polyurethane apex composition suitable for the polyurethane tire, by using the reinforcement of the apex part in the polyurethane tire by using the By reducing the width of the insole, polyurethane tires with excellent steering performance and driving stability were obtained.

본 발명에서 사용되는 폴리우레탄 타이어용 에이펙스 조성물의 제조방법은 다음과 같다.The method for producing an apex composition for a polyurethane tire used in the present invention is as follows.

분자량이 650∼2000인 폴리프로필렌 글리콜(polypropylene glycol) 또는 폴리테트라메틸렌 글리콜 에테르(polytetramethylene glycol ether)와 디이소시아네이트를 1:2의 비율로 혼합하여 반응시켜 프리폴리머를 만들고, 이 프리폴리머와 쇄연장제로서 메틸렌오르소클로로아닐린(methylene-o-chloroanyline) 또는 메틸렌디아민(metnylenediamine)을 1:0.6∼1의 비율로 혼합, 반응시켜 폴리우레탄 타이어용 에이펙스조성물을 제조한다.A polypropylene glycol or polytetramethylene glycol ether having a molecular weight of 650 to 2000 is mixed with a diisocyanate at a ratio of 1: 2 to form a prepolymer, and the prepolymer and methylene as a chain extender are reacted. Orthochloroaniline (methylene-o-chloroanyline) or methylenediamine (metnylenediamine) is mixed and reacted in a ratio of 1: 0.6 to 1 to prepare an apex composition for polyurethane tires.

본 발명에 따른 폴리우레탄 에이펙스 조성물의 제조시에 사용되는 폴리프로필렌 글리콜 또는 폴리테트라메틸렌 글리콜 에테르의 분자량이 650 이하이면, 최종적으로 성형된 에이펙스부의 경도 및 모듈러스가 너무 저하되어 바람직하지 않고, 분자량이 2000 이상이면 경도 및 모듈러스가 너무 높아져 단단해지므로 바람직하지 않다.When the molecular weight of the polypropylene glycol or polytetramethylene glycol ether used in the preparation of the polyurethane apex composition according to the present invention is 650 or less, the hardness and modulus of the finally formed apex portion are too low, which is undesirable. If it is above, since hardness and modulus become too high and hard, it is unpreferable.

본 발명의 에이펙스가 보강된 폴리우레탄 타이어는, 제1도에 나타낸 바와 같이 인너라이너부 성형단계와 비드장착단계 및 카카스코드 위빙(weaving) 단계후에 상기와 같이 제조된 액상의 에이펙스 조성물을 에이펙스 캐버티(Apex cavity)에 주입하여 경화시켜, 에이펙스부를 성형한 다음, 사이드윌, 벨트 및 트레드를 차례로 성형함으로써 제조된다. 당업자라면 본 명세서에서의 설명과 제1도에 의하여 본 발명에 따른 에이펙스부가 보강된 폴리우레탄 타이어를 용이하게 제조할 수 있을 것이다.As shown in FIG. 1, the apex-reinforced polyurethane tire of the present invention is an apex casing of the liquid apex composition prepared as described above after the inner liner part forming step, the bead mounting step, and the carcass cord weaving step. It is prepared by injecting into an Apex cavity to cure, forming an apex part, and then molding the side wheels, the belt and the tread one after another. Those skilled in the art will be able to easily manufacture a polyurethane tire reinforced with an apex part according to the present description and FIG. 1 according to the present invention.

이하 실시예를 통하여 본 발명을 상세하게 설명한다.The present invention will be described in detail through the following examples.

실 시 예Example

분자량 1000의 폴리프로필렌글리콜 1몰과 디이소시아네이트 2몰을 섞어 100℃, 질소 분위기하에서 3시간 동안 반응시켜 프리폴리머를 만들고, 이 프리폴리머 1몰에 메틸렌오르소클로로아닐린 1몰을 혼합함과 동시에 액상의 상태에서 폴리우레탄 타이어 제조공정에 도입하여, 비드장착단계후에 에이펙스 캐버티에 주입한 다음, 타이어 제조공정에 따라 경화, 성형하여 에이펙스가 보강된 폴리우레탄 타이어를 제조하였다.1 mole of polypropylene glycol having a molecular weight of 1000 and 2 moles of diisocyanate are mixed and reacted at 100 ° C. under a nitrogen atmosphere for 3 hours to form a prepolymer, and 1 mole of methylene orthochloroaniline is mixed with 1 mole of the prepolymer. Introduced in the polyurethane tire manufacturing process, injected into the apex cavity after the bead mounting step, and then hardened and molded according to the tire manufacturing process to produce apex-reinforced polyurethane tires.

상기 실시예에서 제조된 에이펙스부가 보강된 폴리우레탄 타이어와 시판되는 기존의 폴리우레탄타이어에 대하여 핸들링성능과 주행안정성을 시험하여 그 결과를 표 1에 나타내었다.The apex part manufactured in the above embodiment was tested for handling performance and running stability of the polyurethane tires and the existing commercially available polyurethane tires, and the results are shown in Table 1.

표 1에 나타낸 각 성능은 전문드라이버의 필링에 의해 측정한 결과로, 기존의 폴리우레탄 타이어의 성능을 100으로 기준했을 때의 성능을 의미하며, 수치가 높을수록 우수함을 나타낸다. 수치 10정도의 성능차이는 일반운전자가 느낄 수 있을 정도의 차이이다.Each performance shown in Table 1 is a result measured by a professional driver's peeling, and means the performance when the performance of the conventional polyurethane tires based on 100, the higher the value is excellent. A performance difference of around 10 is a difference that ordinary drivers can feel.

제 1 도는 본 발명에 따른 에이펙스부가 보강된 폴리우레탄 타이어의 성형공정을 나타낸 도면이다.1 is a view showing a molding process of a polyurethane tire reinforced with an apex part according to the present invention.
